does it make a difference at all in hp from an invida over piper compared to motiv
 

I'm looking at ether spending 254 on a motiv overpipe or 195$ for invida overpipe am i going to notice any difference when i do my e85 tune with the full exhaust setup would having the motiv show any difference compared to the invida and is the invida built with a quality

Same gains(negligible differences). Both are quality parts.

Some people are having fitment issues with the Invidia. My Perrin fit perfectly and had great welds.

Good to know. I don't think the overpipe was out when I made my purchase..otherwise I may have gone with it.
